Patented. June 30, 1908.

Application filed July 3, 1305. Serial No. 263,253.

To all whom it may concern:

Be it known thetl, ltonrnrr H. MILLER, a citizen of the United S'tetes,nnd resident of $t. Louis, Missouri, have invented certain new and usel'ul Improvements in Gloss-Furnaces, of which the following is e. specification containing 3. full, elem, end eXect description, reference being had to the oncompanying drawings, forming at part hereof.

My invention relates to an improved glass furnace, the principal object of my invention being to construct it gloss furnace that plurality of'glnss blowing machines.

A further objectof my invention is to construct av glass furnace, wherein the flow of molten glass from the priumry heating and melting chamber is automatically controlled end regulated by the removal smell quentities of the molten glass by the arms and other devices that deliver the said small quantities of glass, to the glass blowing me chines.

Myinvention consists in a duct or pussege wsy, preferably circular in form, and prowidod with e series of pockets, in which are formed openings, through which the arms of the glass machines travel, in order to gather and carry quantities of the molten from the pockets of the duct to the glass blowing machines. This constant dip dug in and corrying sway of the molten necessarily causes a corresponding movement or low of the molten glass through the duct from. the primary hosting end melting turns 1 My invention further consists ce1.:-un novel features of construction and arrangement of ports l-llillwill be hereinafter shown, described, and claimed.

Figure l it hrwizontul section taken through the duct of my improved gluss fun nece. Fig. 2 is e vertical section taken longitudinully on line 2 B of Fig. l.

Referring by numerals to the accompanying drawings, 1 indicates the main furnzue in which the glass is inched and from which it flows through an outlet :2 in to the elongated chamber or settling basin 3. Lending from the ends of this clmmber Sis a duct l, preferably circular in plnn view, slthough it may be in the shepcof n horseshoe or of an other convenient form. This duct is preferably of uniform width and depth throughout its length although it ney be varied in width and depth at (lifi'erent points to suit different conditions. In the outer well 5 of this duct is formed a series of outwardly extending projections 6, preferably semi-circular, and which form e. corresponding series of pocket-s 7 in the duct l. Those pockets 7 are necess. serily arranged at proper distances apart, in order to accommodate the glass blowing mechines that are arranged around the duct. (See dotted lines Fig. 1.) Forn'ied in the outer wall of each of the pockets is e h0rizontelly arranged opening 8 through which the outer end of the arm travels that convc s the proper quantity of molten glass to the glass blowing machine. If desired, a late such as 9 mey be located upon top 0 the outer wall of the duct below each opening 8, in order to prevent cold air from coming in contact with the surface of the molten glass within the pockets. These plates may be made adjustable if desired. in the nract-icnl use of my improved fur mice the g ess blowing machines are arranged around the duct, at proper distances in front of the pockets, so that the outer ends of the arms such as 10 will travel through the openings 8 mid dip into thepockcts 7. The molten glass from the prinuu'v furnace l will pass through the outlet 2 into the chamber 3 and from thence will llow through the duct 4 and consequently into the pockets -7. VVh'cn the devices for feeding the glass blowing mechines are set in motion the outer ends of the arms in their travel will pass into the pockets 7 and each will curry it proper quantity of molten glass from said. pocket to the blow- O molds oi" the blowing m..rhine, and this con stunt removal of small quantities of molten glass will necessarily induce n flow of the" molten glass through the duct 4 from the cluunbcr .l'und consequcutlv from the priniery heating furnace l. Thus it coustnnt supply; of molten glass is maintained in the duct 4 end pockets 7 in a purely mitometic end iin.turulmsumcr, and no meclnmical dcviccs wluilevcr ore required to deliver the molten gluss'to the ends ol' the arms ll). If desired, openings 11 may be formed in the duct at suitable points in the front end thereof, which openings are normally closed by plugs 123, end when these plugs are removed the molten glass will discharge through said I v I I openings l1 and thus induce a flow of molten glass through the duct and all oartsihereor.

The over flow from the openings ll may he conducted to the primary furnace l 111 any size and in suitable form, it only being essential that the outer wall of said duct be prowlded with the openings through which the devices travel that carry the proper quantities of molten glass to the glessblowing ma chines. In this manner 1 am enabled to accommodate e number of glass blowing mar chines and to properly feed or deliver molten glass to said machines.

I claim:

l. The combination with a glass melting chamber having an outlet, of 21v settling hesin into which she outlet discharges, e eontiriuous covered duet leading from the ends of the settling basin, and there being e plurality of openings Lite seicl duct tl 'ough which the molten glass is removed?" In the duct.

2.; The eornoiiietion i a chamber of a glass furnace, and the outlet therefrom, of a settling basin into which the molten glass discharges from the outlet, e oontiiiuous eov ered duct connected at its ends to the settling basin, pockets formed in the outer wall of the duct, end there being openings through the cover of she duet into said pockets.

The combination with the melting chamber or? a glass furnace, of a continuous over-eel duct leading from the outlet of the melting chamber, there being pockets formed in said duct, and there heirig o enings through the cover of bhe duct into sei pockets.

In testimony whereof, I have signed my name to this speoifioezion, in presence of two SL'ibEICILblQg W1 messes.
